Bruce Wayne: Criminals aren't complicated, Alfred. We just need to figure out what he's after.
Alfred: With all due respect, Master Wayne, perhaps this is a man that you don't fully understand. When I was in Burma, a long time ago, my friends and I were working for the local government. They were trying to buy the loyalty of tribal leaders by bribing them with precious stones. But their caravans were being raided in a forest north of Rangoon by a bandit. So we started looking for the stones. But after six months, we couldn't find anyone who had traded with him. One day I found a child playing with a ruby the size of a tangerine. The bandit had been throwing the stones away.
Bruce Wayne: Then why steal them?
Alfred: Because he thought it was good sport. Because some men aren't looking for anything logical, like money. They can't be bought, bullied, reasoned or negotiated with. Some men just want to watch the world burn.
